We have several type of communications to determined the method of connecting the host on network. There are point-to-point, multipoint and broadcast. This topic will be discriminate multipoint and point to point and broadcast

Point to Point:
This is used in serial(một vài) communication. These type of communications transmitted solely( only one) the station at the opposite end device. No addresses are necessary. Only device connect to only device.
So, it’s the infinite security. Because don’t have another devices connecting in the same time, data only come in one device.
However, it’s very waste money. Simply meaning , we have to spend transmission equipment more than.
Some examples used it:
Multipoint
This is type of connect from one station to several other stations . Datas have been given to other stations that need to send. But don’t have broadcast, just only specific selected stations hear the replicated communication.
It’s the few security. Because, data have to send to many stations and maybe lost in transmission or stealing.
Some examples used it:
Broadcast
Both communication and protocol. It will be send data to all stations have to connecting with it. This always using for information need to send to the stations without knowledge about it.
It doesn’t security. Because, data will dispersal in the network and don’t managed.
Some examples used it:
